AUTOMATIC VACUUM-CUP HUG-0111123.

Specification of Letters Patent.

Application filed April 28, 1919. Serial No. 293,312.

`To all whom t may concern.'

Be it known that I, EDGAR F. PORTER, a citizen of the United States, and resident of Pella, in the county of Marion and State of Iowa, have invented a certain new and useful Automatic Vacuum-Cup IIog-Oiler, of which the following isa specification.

The object of my invention is to provide a hog oiler of simple, durable and inexpensive construction, of the type having a vertical reciprocating rubbing post or bar adapted to operate a vacuum cup feed device so Constructed and arranged that upon the first operation of said rubbing post a full charge of oil will be delivered to the post, and upon subsequent operations only a small charge will be delivered until the post has been allowed to stand without operation for some little time. l

A further object is to provide a tank supporting structure of simple and novel structure.

Still a further object is to provide such a device so arranged that it may be readily and easily mounted on an ordinary support, or removed therefrom. A

With these and other objects in view, my invention consistsv in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying'drawings, in which:

Figure 1 shows a front elevation of alhog oiler embodying my invention.

Fig. 2 shows a side elevation of the same.

Fig. 3 shows a vertical sectional view taken on the line 3-3 of Fig. 1.

Fig. 4 `shows a horizontal sectional view taken on the line 4--4 of Fig. 3; and

Fig. 5 shows a vertical sectional view taken on the line 5-5 of Fig. 1.

In the accompanying drawings I have used the reference numeral 10 to indicate generally the base', which maybe in the forni of a casting having' a pair of upwardly extending parallel ears 11. At the rear part of the base is a bracket member 12 designed to be bolted to an upright 13.

At the forward part of the base is a panshaped member 14 for holding surplus oil that may drop vofi' the rubbing bar hereinafter mentioned.

Mounted on' the upper part of the support 13,. preferably by bolts, is an. oil reservoirl 15, having flanges 16 to receive the bolts 17. Extending forwardly from the lower part of the oil reservoir 15 is a horizontal flange 18, through which is extended a hole 19. At the forward end of the flange 18 is an upwardly extending supporting bracket 20, having a shoulder 21 in its forward part, as illustrated in Fig. 3. Extending transversely across and resting'upon the upper surface of the reservoir 15 1s a bar 22 which extends substantially beyond the sides of said reservoir and has downwardly extending flanges 23 designed to engagc the outer surfaces of the reservoir 15 near the upper edge thereof to hold the bar 22 against any longitudinal movement. The bar 22 may be secured to the reservoir 15 by screw bolts 24, if desired.

Extending downwardly within the reservoir 15, from the central portion of the bar 22, is a cylindrical plunger member 25,

lshown in Fig. 3. Spaced from and surirounding the plunger member 25 on the under surface of the bar 22 is an inverted panshaped member 26, shown in Fig. 3.

I provide a rubbing bar 27, which may have substantially the shape of a half cylinder, provided on its forward surface with alternating overlapping ribs 28, inclined outwardly and upwardly from their overlapping ends, which are located near the forward vertical center of the rubbing bar 27.

At its lower end the bar 27 is formed with a downwardly and rearwardly extending tongue or strip 29 received between the members 11. l The tongue 29 is provided with a vertically elongated slot 30, and a bolt 31 is extended through the ears 11 and the slot 30l in the tongue 29, as illustrated lin Figs; 1, 2 and 5.

At the upper end of the rubbing bar 27y is an upward extension 32 extending slidably upwardly throughthe opening 19, as illustrated in Figs. 2 and 3.

Received within the reservoir 15 is an upwardly `opening cup 33. Leading from the upper part of the cup 33 forwardly a'nd through an opening 34 in the forward wall of the reservoir 15, and thence downwardly and outwardly to the forward surface of the rubbing bar 27, is a trough-shaped member 35 which is rigidly connected with the extension 32 in some suitable way, as by means of screws 36. Y

The plunger member 25 has extending through it a hole or passage 37 leading Patented Sept. 23, 1919.

from the'lower part'iof the plunger upj wardly and to the forward surface thereof to a suitable point' for discharging tothe trough 35, which inclines from` thence forvwardly and downwardly.vr

In the lower part of the cup 33 the wall of said-cup is provided with an vopening 38.

I provide for use with my improved hog oiler an oil or vermicide container comprising a 'cylindricalcan 39, which in use with my device is inverted, as illustrated in Fig. 3. VThe container' 39 has a cylindrical extension 40, which, when the container is in position for use, extends downwardly into Ythe reservoir 15 and is designed'to conduct oil or the like from the -container 39 into the lower part of the reservoir'l.

The partsl are soI arranged that the lower -end oftheextensionll() is below the lower edge of the opening 34, so that the fluid oil or the like forms a liquid sealfor prevent- 'ingthe escape of the contents of the container y39 except as the contents of the reservoir 15 are deliveredv to the rubbing bar 27.

-The -.parts are also constructed 4so that when the rubbing bar 27 is in its normal lowered position Lthe bottom of the cup 33 `is considerably belowthe bottom of the l plunger 25, and the bottom of the plunger 25 is at least slightly above the-hole 38, so lthatthecrude oil or, other vermicide or contents ofthe container 39 and reservoir 15 will pass through the opening 38 into the lower part of the cup A33.

The vcontainer 39 is placed with the member 40 up, Vand filled therethrough. f Thereafter Yit is inverted and supported on the bar 22 and the'bracket 2.0. A yoke 41 `may be extended ov'er the container 39 and its ends may be extendedl through the ends of 'the bar 22 and locked in place vby means :ofwing nuts42, for holding the container against accidental removal.

ItV will be obvious that the contents of the -container 39 will flow down through the extension 40-untilthe reservoirl 15 fills upV to the lower end of the member 40 whereupon the liquid willfform. a seal and prevent the i Vfurther discharge of suchfliquid from the container.

When the hog or other animal comes to the device and rubs against the rubbing ybar 27 it will be noted that said barv is capable bing bar 'is movedV upwardly yit carries with it, the cup 33, the lower part of which will have been filled through-thefhole38 with the vermicide :or crude oil or other'liquid.

VVVhenthe cup `moves upwardlyits contents will be forcedout through the passage 37 to .thetrough-shaped memberf35, from whence V the liquid will k,be discharged "upon Vthe 'Y upper vfront -surface of the rubbing bar '27.

gri-...win beamed ,that at 1an-.beginning of' i`the upward-movement of V`the cupi w33, .the

I find that a device of this kind is .economiical for the reason that when the rubbing bar is reciprocated there is first delivered to the bara full charge of the liquid, and thereafter only a small charge is Adelivered upon each raising of the rubbing bar until the animal allows the rubbing bar V*to-'remain quiet for a considerable period. I am thus able to a considerable extent to avoid waste of the oil or other contents of the reservoir 15.` l

With a device of this kind there is no danger of an animal moving the rubbing lbar to position where there is a constant discharge from the reservoir.

The parts are of very simple and inexpensive construction, and vthe -whole de;-

-vice may be readily and easily mounted. on

a pcst or supported anywhere in-the feeding yar The bar 22 furnishes a means Vfor supporting the plunger member. 25, and also `for supportingand holding the container 39 in its proper position. The bracket 20 also assists in holding the container inpos'ition, and serves as a guard or protection for` the trough-shaped member. 35 which conducts the liquid from the passage 37 to the upper front surface of the rubbing bar.Y f

The oil is heldby vacuumto the, required depth inthe reservoir, and thevacuum cup holds'enough to supply therrubbing-bar at the first operation thereof,after whichvery little oil is supplied untilV the animal'quits rubbing. ,Y Incidentally, the pan-shaped portion 14 of the basecatches all the drippings oflithe bar, and this oil thus caught is applied to the under parts of the hog.

Some changes maybe made inl' the construction and arrangement of the various parts of my improved hog oiler without departing from the essential spirit and purpose Vof myinvention, and 'it is my intention .to

coverjby my claims any modified forms of structure or use of vmechanical*equivalents which may be reasonably included within their scope.
